Fixed torque electric wrench, also known as adjustable torque electric wrench, is a kind of electric wrench. Its main feature is that the torque can be set and the torque is adjustable. It is mainly used in the steel structure installation industry to install high-strength bolts of steel structure. High-strength bolts are used to connect steel structure contacts, usually in the form of bolts.

Advantages and disadvantages of fixed torque electric wrench

一般来说，高强度螺栓在拧紧之前须拧紧，每个阶段都要求有严格的扭矩要求。本实用新型涉及一种定扭矩必威西汉姆联官网g1线路，适用于高密度大六角头高强度螺栓的端部。

Generally speaking, high-strength bolts must be tightened before tightening, and strict torque requirements are required at each stage. The utility model relates to a fixed torque electric wrench, which is applicable to the end of high density large hexagon head high strength bolts.

目前对定扭矩必威西汉姆联官网g1线路的研究多集中在兼具定值和过载故障功能的数字式显式定扭矩必威西汉姆联官网g1线路，并通过LCD显示窗口的人性化设计受到用户的欢迎。此外，还有扭矩值监控终端、峰值设定和报警功能、无线传输功能、与已安装的无线传输终端通信、数据记录和管理。

At present, the research of constant torque electric wrench is mostly focused on the digital explicit constant torque electric wrench with both constant value and overload fault functions, and it is welcomed by users through the humanized design of LCD display window. In addition, there are torque value monitoring terminal, peak setting and alarm function, wireless transmission function, communication with installed wireless transmission terminal, data recording and management.

从传统的手指扭矩扳手到各种社会功能的数字式显式固定扭矩必威西汉姆联官网g1线路，随着信息技术的发展可以实现了质的飞跃。现有的定扭矩必威西汉姆联官网g1线路具有以下几个优点:①技术不断成熟，性能比较稳定;（2）人性化管理操作系统界面;强大的数据分析处理主要功能等。

From the traditional finger torque wrench to the digital explicit fixed torque electric wrench with various social functions, with the development of information technology, a qualitative leap can be achieved. The existing fixed torque electric wrench has the following advantages: ① the technology is constantly mature and the performance is relatively stable; (2) Humanized management operating system interface; Powerful data analysis and processing main functions.

固定扭矩必威西汉姆联官网g1线路缺点:系统进行组件多任务复杂性文献中提出了作为一种人工智能扭力扳手系统，包括企业电子标签、扭力扳手、信息资源管理会计软件等，通过建立一系列发展智能手机芯片来完成一个必要的功能。使用扳手系统时，须能够同时启动计算机并对螺栓信息编号，创建网络信息安全记录学生管理分析软件，并在相应的螺栓上粘贴电子标签。力矩扳手的功能需要在教学准备教育工作任务完成后我们才能充分发挥，效率低，操作过程复杂。类似的扭力扳手结构比较复杂。准确性和价格困难目前，市场上的定扭矩必威西汉姆联官网g1线路在精度和价格上都是难题。高精度扳手一般是数字式定扭矩必威西汉姆联官网g1线路，进口产品，价格水平一般来说较高。价格低的是扭力针扳手结构相对简单，精度低，难以满足人们使用不同要求。这也是扭矩扳手在相关知识领域方面没有能力得到广泛应用的原因之一。

Disadvantages of fixed torque electric wrench: the system carries out the multi-task complexity of components, which is proposed in the literature as an artificial intelligent torque wrench system, including enterprise electronic label, torque wrench, information resource management accounting software, etc., and completes a necessary function by establishing a series of smart phone chips. When using the wrench system, you must be able to start the computer and number the bolt information at the same time, create the network information security record student management analysis software, and paste the electronic label on the corresponding bolt. The function of torque wrench needs to be fully played after the teaching preparation and education tasks are completed. It is inefficient and the operation process is complex. Similar torque wrenches have complex structures. Accuracy and price difficulties At present, the precision and price of the fixed torque electric wrench on the market are difficult. High-precision wrenches are generally digital fixed-torque electric wrenches, which are imported products, and the price level is generally high. The low price is that the torque pin wrench has relatively simple structure and low precision, which is difficult to meet the different requirements of people. This is also one of the reasons why torque wrench is not able to be widely used in relevant knowledge fields.

智力低下。现有的固定扭矩必威西汉姆联官网g1线路具有应用扭矩值和监测扭矩值的能力，但需要手动设置多少扭矩值才能适用于不同规格的螺栓。不同螺栓的预紧力矩值可参照有关手册或公式计算。目前，只有一些特殊行业的产品有预压螺栓的信息。普通螺栓预紧力的具体值是根据经验确定的，这是阻碍使用定扭矩必威西汉姆联官网g1线路的原因之一。

Mental retardation. The existing fixed torque electric wrench has the ability to apply torque value and monitor torque value, but how many torque values need to be manually set to apply to bolts of different specifications. The pre-tightening torque of different bolts can be calculated by referring to relevant manuals or formulas. At present, only some products of special industries have the information of preloaded bolts. The specific value of pre-tightening force of ordinary bolts is determined based on experience, which is one of the reasons preventing the use of fixed torque electric wrench.
